A carrier‐mediated countertransport process for the extraction of amino acids is reported. The permeation of l ‐Phe through a liquid membrane, constituted by a solution of ALIQUAT‐336 in toluene and supported by a hydrophobic microporous membrane, was studied. The best operating conditions were deducted by considering the effect of hydrodynamic factors, carrier concentration in the membrane phase, etc . The effect of impurities such as phosphates and tyrosine on the flux of Phe and selectivity of the carrier was evaluated.
